In the late 1970s or early 1980s I read a children's/YA novel about a young woman who wanted to be a ballet dancer. She suffered an accident which I recall as being hit by a train crossing a railway track, and she lost the toes on one foot. She thought she would never dance again but somehow (implausibly) she did dance again.
All the other books I recall from childhood definitely exist but I cannot find any trace of this book or anyone that remembers it. I asked AI but they unhelpfully sent me on a wild goose chase by making up a book and an author that doesn't exist!
Does anyone remember a book that matches this description? I know there are other ballet/accident/convalescing books but the train and the toes are the thing I remember the most about this book but I'm starting to wonder if I dreamed it!
